St. Justin Martyr on the Soul After Death

For the passage, ‘Deliver my soul from the sword, and my only-begotten from the hand of the dog; save me from the lion’s mouth, and my humility from the horns of the unicorns,’ is indicative of the suffering by which He should die, i.e., by crucifixion. For the ‘horns of the, unicorns,’ I have already explained to you, are the figure of the Cross only. And the prayer that His soul should be saved from the sword, and lion’s mouth, and hand of the dog, was a prayer that no one should take possession of His soul: so that, when we arrive at the end of life, we may ask the same petition from God, who is able to turn away every shameless evil angel from taking our souls. (Dialogue with Trypho 105)
